You may qualify if…

Subject's parent or legal guardian has provided written informed consent and HIPAA authorization (if applicable) prior to any VBP15-LTE long-term extension study-specific procedures;
Subject has previously completed study VBP15-003 up to and including the Week 24 Final assessments, prior to enrolling in the VBP15-LTE study at the conclusion of the VBP15-003 Week 24 Visit [Note: if entering the dose-tapering period, subject is enrolling within 8 weeks after the VBP15-003 final visit following dose-tapering]; and
Subject and parent/guardian are willing and able to comply with scheduled visits, study drug administration plan, and study procedures.

You may not qualify if…

Subject had a serious or severe adverse event in study VBP15-003 that, in the opinion of the Investigator, was probably or definitely related to vamorolone use and precludes safe use of vamorolone for the subject in this long-term extension study;
Subject has current or history of major renal or hepatic impairment, diabetes mellitus or immunosuppression;
Subject has current or history of chronic systemic fungal or viral infections;
Subject has used mineralocorticoid receptor agents, such as spironolactone, eplerenone, canrenone (canrenoate potassium), prorenone (prorenoate potassium), mexrenone (mexrenoate potassium) within 4 weeks prior to the first dose of study medication;
Subject has evidence of symptomatic cardiomyopathy. [Note: Asymptomatic cardiac abnormality on investigation would not be exclusionary];
Subject is currently being treated or has received previous treatment with oral glucocorticoids or other immunosuppressive agents [Notes: Past transient use of oral glucocorticoids or other oral immunosuppressive agents for no longer than 3 months cumulative, with last use at least 3 months prior to first dose of study medication, will be considered for eligibility on a case-by-case basis. Inhaled and/or topical glucocorticoids prescribed for an indication other than DMD are permitted but must be administered at stable dose for at least 3 months prior to study drug administration];
Subject has used idebenone within 4 weeks prior to the first dose of study medication;
Subject has an allergy or hypersensitivity to the study medication or to any of its constituents;
Subject has severe behavioral or cognitive problems that preclude participation in the study, in the opinion of the Investigator;
Subject has previous or ongoing medical condition, medical history, physical findings or laboratory abnormalities that could affect safety, make it unlikely that treatment and follow-up will be correctly completed or impair the assessment of study results, in the opinion of the Investigator
Subject is currently taking any investigational drug, or has taken any investigational drug other than vamorolone within 3 months prior to the start of study treatment.
Note: Subjects may be re-evaluated if ineligible due to a transient condition which would prevent the subject from participating.
